Definitions

  • the invention relates to a locking unit for a vehicle seat with a pivotably mounted rotary latch for locking with a bolt, the rotary latch having a rotary latch hole for pivotably mounting on a bearing bolt protruding through the rotary latch hole, and a latching pawl which, in the event of a crash, secures a locked state of the locking unit by the rotary latch being supported on a first contact point on the latching pawl.
  • the invention also relates to a vehicle seat with the locking unit.
  • a locking unit of the type in question for a vehicle seat comprises a pivotably mounted rotary latch for locking with a bolt.
  • a latching pawl which is mounted pivotably about another pivot axis secures the rotary latch in the locked state.
  • a tensioning element which is referred to as a tolerance-compensating pawl exerts a closing moment on the rotary latch and thereby eliminates play present between the rotary latch and the bolt.
  • DE 20 2011 100 040 U1 likewise discloses a locking unit for a vehicle seat.
  • the rotary latch of this locking unit has a recess which differs from the circular shape and is approximately in the shape of an elongated hole and by means of which said rotary latch is mounted pivotably on a bush or a bearing bolt.
  • the latching pawl and the tensioning element are arranged so as to be pivotable about the same axis and axially offset next to each other on a bearing bolt and interact with the rotary latch.
  • first of all only the latching pawl secures the rotary latch by the rotary latch being supported on a contact point on the latching pawl.
  • the crash load which is transmitted by the bolt to the rotary latch in the event of a crash is absorbed here by the contact point of the rotary latch with the latching pawl.
  • the rotary latch In the event of a high crash load, the rotary latch is displaced relative to the bearing bolt along the recess which is approximately in the shape of an elongated hole until it comes to bear against the housing of the locking unit. This gives rise to a second contact point which can additionally absorb the crash load.
  • the invention is based on an object of improving a locking unit of the type mentioned at the beginning, in particular of specifying an alternative possibility for increasing the load-absorption capacity in the event of a crash, in order to increase the crash safety of a vehicle seat.
  • a locking unit of the type in question for a vehicle seat comprises a pivotably mounted rotary latch for locking with a bolt, wherein the rotary latch has a rotary latch hole for pivotably mounting on a bearing bolt protruding through the rotary latch hole, and a latching pawl which, in the event of a crash, secures a locked state of the locking unit by the rotary latch being supported on a contact point on the latching pawl.
  • the rotary latch of the locking unit has at least one cutout region which, in the event of a crash, permits a deformation of the rotary latch, wherein the cutout region is arranged spaced apart in the radial direction from the rotary latch hole.
  • the cutout region is therefore formed separately from the rotary latch hole and is separated therefrom, for example, by a web.
  • the rotary latch Owing to the fact that the rotary latch has a cutout region which, in the event of a crash, permits a deformation, and which is arranged spaced apart in the radial direction from the rotary latch hole, the rotary latch can be displaced in the event of a crash until said rotary latch comes to bear against the housing of the locking unit, thus producing a second contact point which can additionally absorb the crash load.
  • the rotary latch advantageously executes a displacement of this type, i.e. a translatory movement and/or a tilting movement, in order to reach the housing.
  • the cutout region is designed as a continuous opening in the axial direction.
  • a cutout region designed in such a manner can be produced relatively simply, for example, by means of punching.
  • the cutout region is designed as a notch.
  • the rotary latch advantageously has a hook mouth for receiving the bolt.
  • the cutout region is arranged on that side of the rotary latch hole which faces away from the hook mouth.
  • the rotary latch has at least one load-relieving region which is provided on that side of the rotary latch hole which is opposite the cutout region.
  • the load-relieving region assists the deformation of the rotary latch.
  • the rotary latch and the latching pawl are arranged within an at least partially closed housing.
  • the cutout region preferably runs approximately in a semicircle around the rotary latch hole.
  • a vehicle seat comprising at least one locking unit according to the invention.

  • the first bearing bolt 51 therefore runs horizontally in the transverse direction.
  • the preferably metallic first bearing bolt 51 is riveted or calked to the side plates 16 , 18 .
  • the first bearing bolt 51 is preferably designed in the form of a hollow cylinder in order to receive a fastening means, for example a screw, by means of which the locking unit 10 is fastened to the backrest 3 during the installation.
  • the second bearing bolt 52 is also inserted into respective bearing bores 13 in the side plates 16 , 18 and protrudes perpendicularly from the basic surfaces of the side plates 16 , 18 .
  • the second bearing bolt 52 therefore likewise runs horizontally in the transverse direction.

  • the second bearing bolt 52 is preferably designed in the form of a hollow cylinder in order to receive a fastening means, for example a screw, by means of which the locking unit 10 is fastened to the backrest 3 during the installation.
  • a tensioning element 40 is mounted pivotably on the second bearing bolt 52 .
  • the tensioning element 40 has a tensioning element hole 44 which, in the present case, is circular and is penetrated by the second bearing bolt 52 .
  • the tensioning element 40 is pretensioned toward the rotary latch 20 by means of a third spring 73 .
  • the tensioning element 40 exerts a closing moment on the rotary latch 20 owing to the pretensioning by the third spring 73 as a securing element.
  • the tensioning element 40 has a tensioning surface 41 which is curved eccentrically with respect to the second bearing bolt 52 and is in non-self-locking contact with the functional surface 22 of the rotary latch 20 .
  • the tensioning surface 41 is curved in the shape of an arc of a circle and is of convex design.
  • a latching pawl 30 is arranged on the second bearing bolt 52 axially next to the tensioning element 40 and is likewise mounted pivotably on the second bearing bolt 52 , i.e. in alignment with the tensioning element 40 .
  • the latching pawl 30 has a latching pawl hole 34 which, in the present case, is circular and is penetrated by the second bearing bolt 52 .
  • the latching pawl 30 is pretensioned toward the rotary latch 20 by means of a second spring 72 .
  • the latching pawl 30 is arranged adjacent to the first side plate 16 and, in the present case, the tensioning element 40 is arranged adjacent to the second side plate 18 .
  • the latching pawl 30 and the tensioning element 40 are coupled by empty travel for carrying-along purposes, for example by means of a slot and pin guide or by means of an axially protruding driver.
  • the latching pawl 30 has a latching surface 31 which is in the vicinity of the tensioning surface 41 of the tensioning element 40 .
  • the latching surface 31 is positioned spaced apart from the functional surface 22 of the rotary latch 20 .
  • the latching surface 31 is curved in the shape of an arc of a circle and is of convex design, but may also be planar.

  • the cutout region 25 here is arranged spaced apart in the radial direction from the rotary latch hole 24 .
  • the cutout region 25 is therefore formed separately from the rotary latch hole 24 and, in the present case, is separated therefrom by a web.
  • the cutout region 25 therefore does not have any connection with the rotary latch hole 24 .
  • the cutout region 25 may also be designed in a different manner.
  • the cutout region 25 can be designed as a notch which extends from the surface of the basic body of the rotary latch 20 into the basic body, but not through the latter.
  • the semicircular cutout region 25 can also be interrupted by one or more webs.
